Answer:
1.32 L
Solution:
According to Boyle's Law, " The Volume of a given mass of gas at constant temperature is inversely proportional to the applied Pressure". Mathematically, the initial and final states of gas are given as,
P₁ V₁ = P₂ V₂ ----------- (1)
Data Given;
P₁ = 0.865 atm
V₁ = 1.25 L
P₂ = 0.820 atm
V₂ = ??
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (0.865 atm × 1.25 L) ÷ 0.820 atm
V₂ = 1.318 L ≈ 1.32 L
Result:
As the Pressure has decreased from 0.865 atm to 0.820 atm, therefore, Volume got increased from 1.25 L to 1.32 L.
